Description:The 3D FlipBook – PDF Embedder, PDF Flipbook Viewer, Flipbook Image Gallery plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the send_post_pages_json() function in all versions up to, and including, 1.16.17.

WordPress 3D FlipBook - PDF Flipbook Viewer, Flipbook Image Gallery plugin versions <= 1.16.17 contain a missing authorization vulnerability in multiple AJAX endpoints. The fb3d_send_posts_in, fb3d_send_post_pages, fb3d_send_posts_in_pages, fb3d_send_posts_in_first_page, and fb3d_send_post_first_page handlers are registered with wp_ajax_nopriv hooks but fail to verify the post status of requested flipbook entries. This allows unauthenticated attackers to retrieve full metadata, PDF URLs, and configuration data of private, draft, and password-protected flipbook posts.
